Dr. Daniel Pine and his colleagues used magnetic resonance technology to watch the brain activities of 34 healthy young people ages nine to 17 years old. The participants rated their interest in communicating with teenagers based on how their faces appeared on computer screens. Then they were asked to appraise the same faces two weeks later.
Older females in the study showed more brain activity than younger ones did in the parts of the brain that process social emotion. Older males' reactions were not that much different than those of younger males.
This study appears in the journal Child Development.
